To all whom t may concern.'

Be it known that I, WESLEY W. Seurin TLER, a citizen of the UnitedStates, residing at Springi'ield, in the county of Clark and VState ofOhio, have invented certain new and useful Improvements inOil-Reservoirs for Internal-Combustion Engines, of which the followingis a specification.

This invention relates to improvements in oiling devices for internalcombustion engines, it more particularly relates to the arrangement ofthe oil supply for the engine.

The object of the invention is to provide an oil reservoir so locatedthat the oil will be maintained in a freely flowing condition by theheat of the cooling water.

A further object of the invention is to provide an oil reservoir solocated in the water reservoir as to not only furnish an adequate supplyof oil but also to act as a deflector for the water during itscirculation through the reservoir to prevent the same from splashing outof the supply opening.

In the accompanying drawings Figure 1 is a longitudinal section of somuch of an internal combustion engine and its water jacket and reservoiras is necessary to illustrate my improvements, my improved oil reservoirbeing shown applied thereto.

Fig. 2 is an enlarged section of a portion ofhthe water reservoir and ofthe oil reservoir.

Fig. 3 is a front view in detail of the water reservoir showing the oilreservoir in dotted lines.

The engine which I have shown my invention applied to is of thehorizontal stationary type, 1 representing the base upon which ismounted the crank case 2, having bearings for the crank shaft 3, whichcarries the fly wheels l (one only being shown in the present case) onthe exterior of the casing, the crank shaft being connected in the usualway with the piston rod 5 of the piston 6.

The cylinder 7 is in the present case integral with the crank case andprovided with the usualform of integral water jacket 8. The waterreservoir which supplies water to the jacket is indicated by 10 and hasan opening 9 in its top through which 'the water is supplied to thesame. This water reservoir is in the present case locatedsubstantiallyabove the crank case so as to furnish a better balance for the engine,the floor 11 of the reservoir separating the same from the interior ofthe crank case.

My improvement consists in locating in this water reservoir an oilreservoir 12. This oil reservoir is cast integral with the waterreservoir and extends across the entire width of the same at the upperforward portion thereof, the rear wall of the oil reservoir beingadjacent to and extending downwardly from the water supply opening 9. Anopening extending into the upper part of the reservoir 12 and closed bya plug 13 is provided for replenishing the reservoir with oil and asuitable valve 14 of well known construction communicating with thelower portion of the oil reservoir is provided for conveying the oil tothe parts to -be lubricated.

From the construction explained it will be seen that the oil in the oilreservoir will be kept in a heated condition by the water and by itspeculiar location it also acts as a deiiector for the water to preventthe same from splashing out through the opening 9.

Further, the particular location of the oil reservoir is one where itwill be brought into intimate contact with the water which is firstheated so that the oil will be quickly brought to a condition to flowfreely, the circulation of the water being upwardly along the forwardwall of the water reservoir.

Having thus described my invention, I claim Vl. In an internalcombustion engine, the combination, with a cylinder and its waterjacket, of a water reservoir communicating with said jacket, and anintegrally formed oil reservoir located in said water reservoir.

2. In an internal combustion engine, the combination, with a cylinderand its water jacket, of a water reservoir communicating with saidacket, and an oil reservoir located .in said reservoir in the path ofthe water circulating from said reservoir and in proximity to saidjacket.

3. In an internal combustion engine, the combination, with a cylinderand its water jacket, of a water reservoir communicating with said waterjacket, and an oil reservoir in said water reservoir formed integrallytherewith, said oil reservoir extending across the upper forward portionof said water reservoir.
